Consider the points of the sides to be x1,y1 and x2,y2 respectively. Now plug the x value into one of the altitude formulas and solve for y: Therefore, the altitudes cross at (–8, –6). The altitude can be inside the triangle, outside it, or even coincide with one of its sides, it depends on the type of triangle it is: . Circumcenter of a triangle is the point of intersection of all the three perpendicular bisectors of the triangle. Suppose we have a triangle ABC and we need to find the orthocenter of it. We know that the formula to find the area of a triangle is $$\dfrac{1}{2}\times \text{base}\times \text{height}$$, where the height represents the altitude. In a triangle, an altitude is a segment of the line through a vertex perpendicular to the opposite side. To make this happen the altitude lines have to be extended so they cross. The three (possibly extended) altitudes intersect in a single point, called the orthocenter of the triangle, usually denoted by H. The orthocenter lies inside the triangle if and only if the triangle is acute (i.e. The orthocenter of a triangle is denoted by the letter 'O'.
